| Abstract: | Effects of the resonant Bragg scattering of magnetostatic backward volume waves on the periodic structure of a conductive
meander pattern with an alternating current are analyzed theoretically and compared with experiment. It is shown that unlike
a static grating, a dynamic grating causes a frequency shift of the scattered wave. It is proposed that this phenomenon be
utilized for effective control of the intermodal conversion of magnetostatic waves.
